by | Jun 24, 2026

These are the best Signaturit alternatives in 2026:

  1. Legalpin
  2. DocuSign
  3. Adobe Acrobat Sign
  4. Viafirma
  5. Tecalis
  6. Lleida.net

Signaturit was acquired by the Namirial group in 2025, backed by Bain Capital and PSG Equity. The integration into a larger European trust services group has brought changes to commercial policy and the product roadmap that are prompting many companies to evaluate alternatives.

At the same time, the entry into force of regulations such as Law 1/2025 MASC has expanded certification requirements beyond electronic signature, opening the market to solutions that combine signature and certified communications in a single environment.

The 8 best Signaturit alternatives

1. Legalpin

Legalpin is the certified digital messaging platform covering the widest range of functionalities for companies that need both electronic signature and communications with probative value. It integrates simple, advanced and qualified electronic signature alongside certified email, buromail, certified SMS and certified invoice, all from a single environment with an open API.

For companies managing contracts, employee notifications, payment claims or critical client communications, combining signature and certified email in the same flow eliminates the need to coordinate multiple providers. Legalpin operates under the eIDAS Regulation and Law 6/2020, with qualified trust service providers that generate evidence files downloadable as PDF at any time.

2. DocuSign

Its deployment is particularly strong in large enterprises with high-volume signing workflows that require integrations with CRM, ERP and productivity tools such as Salesforce, Microsoft 365 or Google Workspace.

The platform offers simple and advanced electronic signature with eIDAS validity in Europe, although the qualified level requires additional configuration through external certificate providers. The per-user cost is higher than other European market alternatives, and localised Spanish-language support has less depth than that of Spanish-origin providers.

Legal validity eIDAS in Europe, recognised in over 180 countries
Integration API, native connectors with Salesforce, Microsoft 365, Google Workspace
Evidence file Completion certificate with activity log

It offers simple and advanced signature with eIDAS validity, and integrates with Microsoft 365, Salesforce and SAP. Like DocuSign, the qualified level under eIDAS requires external certificate management. The pricing model is oriented towards individual users or small teams, with costs that scale significantly as send volume increases.

Why look for a Signaturit alternative

Signaturit was acquired by the Namirial group in 2025, backed by private equity funds Bain Capital and PSG Equity. Integration into a larger-scale European trust services group has brought changes to commercial policy and the product roadmap, including pricing modifications and adjustments to the plans available for existing customers.

At the same time, the entry into force of Law 1/2025 MASC has expanded documentary certification requirements beyond electronic signature. Companies that previously covered their certification needs with signature alone now also need certified email or buromail to comply with the requirement to certify the out-of-court resolution attempt prior to any legal claim. That combination of factors is driving many companies to evaluate alternatives that cover a more complete cycle or offer a better functionality-to-price ratio for their profile.

What to assess before switching platform

The first criterion is the level of signature required. Most commercial contracts between companies are valid with advanced electronic signature, but some legal acts require qualified signature, equivalent to a handwritten signature under eIDAS. Not all providers offer all three levels.

The second criterion is whether the company needs signature only or also certified communications. Law 1/2025 MASC requires certifying the out-of-court resolution attempt before any legal claim, which requires a certified communication channel independent of the signature. If the company manages payment claims, employment notifications or contract modifications, it needs a provider that also covers that channel.

The third criterion is technical integration. Most providers offer a REST API, but the depth of native connectors with the systems the company already uses, CRM, ERP, HR tools, determines the real implementation cost.

Frequently Asked Questions (FAQs)


No. The qualified signature has direct equivalence to a handwritten signature under the eIDAS Regulation and is automatically recognised in all EU courts. The advanced signature is valid but requires the company to provide additional evidence in the event of a dispute to prove the signer’s link to the signature.


Contracts signed digitally on any eIDAS platform retain their legal validity regardless of whether the company continues using that provider. The evidence file downloaded at the time of signing is the legal proof, not continued access to the platform.


There is no general obligation to use qualified signature for employment contracts, but recent case law requires companies to prove that the employee received and had access to the signed document. An advanced signature with robust evidence, or a signature combined with certified sending, covers that requirement.


Yes. Legalpin allows each service to be used independently, including electronic signature only. The advantage of contracting them together is that the signing flow and certified sending are integrated in the same evidence file, simplifying document management and strengthening the probative position in the event of a dispute.


The standard retention period is five years with most providers, matching the general limitation period for personal actions under the Spanish Civil Code. It is advisable to download evidence files at the moment of issue and not rely solely on the provider’s storage.
